Application led March 3,1, 1926. Serial No. 98,910.

- My invention relates ingeneral to refrigerators and more particularly to a refrigeratnig` body for ice cream trucks.

- It is well known to those skilled in the art,

that in icecream trucks where brine yis used 2 as the refrigerant, thebrine penetrates the woodworkof the body and comes to the outer paintedI surface-thereof, with theresult that the brine partly or wholly destroys the paint thereon.l Furtlier1nore,due to the difference in temperature between thefbody and the outside atmosphere, there will be a sweating or a condensing of the humidity of the air upon the surface ofthe present day ice cream truck body, which also deteriorates the paint on the outside surface of the same.

It has been an object of. my invention to provide a body in which itl shall be Apractically impossible for the brine to reach and penetrate theoutside wall and surfacethereof.4 l Y Y Another object has been to provide a device whereby sweating upon the outside surface ofthe bod-y shall be prevented.V y Furthermore, by means ofzmy device,I get possible in this type of refrigerator7 and I am able to retain this temperature for a greater j length of time.

The objects above pointed out have been accomplished by the device shown in the accompanying drawing. In the drawing, the single figure is a perspective view of my invention, with'portions broken away and sectioned.

My device comprises an inner refrigerating i of longitudinal partitions 9, with cross parti-` tions 10 in each of which are formed perforations 11. It is preferablethat the partitions 'do not eXtendrclear to the top of the pan. By this means and by means of the apertures 11, thesurging of the brine and ice, due to the motion of the truck, 'is retarded.

Surrounding each of the inner walls 6 and each of the side walls of the brine tankv'is a cork wall 12. It is preferable to provide insulating paper on each side of this cork wall as is customary. An outer cork wall 18 is provided and is arranged in interspaced relanailing strips 14 are arranged between the cork walls 12 and 13-andv these form spaces 20 between the walls'. The cork ,walls 13 are alsov preferablyl faced with insulating paper. A

. tion with the cork wall 12. 'plura-l'ityof l i plurality of nailingstrips l'are provided on the-,outside-of-,the cork wall 13, and to these nailing strips is secured veach of the outer side" walls-16of the body. The nailing' strips "15 serve to keep the wall 16 of the body in interspaced relation Vwith each of' the outerV whichis not broken by one'or more air spaces.

It is thisrstructure which prevents the brine from penetrating through the walls ofthe body and reaching the outer surface ofthe i outer walls 16. A top 17 is provided forthe spaces 19 `are ,open only at theirybottorns.

Byv this provision, the airin the spacesl19 ywill be kept at such a temperature' that sweating of the walls16 will be prevented, but no circulation of air, which is sufficient toraise the temperature of the refrigerating Vcompartment 5 any appreciable degree, will be possible. By leaving the bottom of the spaces 19 open, any condensation which occurs on the outside of the outer cork walls 13will be free to run to the bottoms of the spaces Y19 and drip from the lower edges of the walls lvwithout coming in contactwith the outer walls 16, thus preventing any accuinur lation ofcondensation in the spaces 19. The

spaces 2O between the outer cork wallsV 13 i refrigerator com- 1 without departing from` the spirit of my invention, or the scope of the appended claims, and I do not, therefore, wish tobe limitedV to the exact embodiment herein contained.

thusdescribed my invention what tion with eachof the outer cork walls, the

Spacesbetween the inner and outery cork walls being closed and separated fromrthe spaces between-the outer cork walls and the outer side wal1sthe spaces between the outer fwalls and the outer cork walls beingrseparate and non-communicating and 'open only at the bottom, Vwhereby both'sides of the outer Walls will be subjected to atmospheric temperature. Y

2; Arefrigerator comprising a top, a subfloor, an inner refrigerator side wall at each sideV of the refrigerator, an inner cork side wall in contact with each inner side wall,

'an outer cork side wall'` in spaced relation vwith each inner cork wall, the inner and outer cork side walls extending from the top to the subfloor, thus forming sealed air spaces therebetween, and an outer side wall in spaced relation with each outer cork wall, each of they outer sidewalls extending from the top to a point substantially opposite the outer edge of the subfloor, wherebyA the space .formed between each outer side wall and each outer cork'v wall is Aopen only at the bottom for the admission of atmospheric air. e

outer cork side wall inspaced relation with each inner cork wall, the iiinerand vouter cork side walls extending from the top tothe subfloor, thus forming sealed air spaces therebetween, andanouter side wall in spaced relation wit-h each outert cork wall, the space between the outer side wall and the outer cork wall at each side of the refrigerator being vseparate and non-communicating, each of the outer side walls extending from the top to a point substantially opposite the outer edge of the subfloor, whereby the space formed between each outer side wall and each outer cork wall'isb open only atthefbottom u for the admission of atmospheric air. l
